In the general class ofseals or closures to i which my linvention applies it has beenold and accepted practice to form upon the: mouth of" the container a closure or. sealing.

member so conforming to the structure of the mouth as to interlock therewith.v

In such easily deformable closures as those fof non-metallic material, sucient deformation for removal is possible without such distortion as to render detection of replacement easy. y

While my invention iscapable of a -wide tratlve of my invention a popular type of closure for milk bottles such as is quite generally used in the urban delivery of milk and cream. While I have selected a rather specie form of closure as illustrative' of my 1n vention it will be und `erstood'that` such. is"

illustrative rather than limiting and that various modifications in type and lstructure may be employed withoutdeparting from the spirit of my invention.` l

Ingeneral m invention contemplates the combination with closures of such typesy with a positive locking' member expansible or otherwise extensible vto compel positive interengagement of the closure and the containermouth or neck.

-I invite attention to'the combination of the'l closure and the container of well known applied.

The/container type selected as above stated is the So-called milk bottle type and the closure type selected is the pulp or paper closure generally acceptedl as the most eco- `of standard sealing by which the range of usefulness I have selected as illusthe specific corresponding parts, and in the nomical Iand best to Lcom'litions of 'lac-'- tic distribution.rv

In the drawings I have indicated at 1 the Y neck of such a container having a mouth 2 and an external bead or lip 3. Internally the delivery orifice is grooved to form a shoulder 4 which under most State laws vlmeans a definite filling level 'indicating the' its lower edges by the shoulder or shelf ,-4 I

and 'on its upper ed e by the inward or overhangin bead v o the bottlemouth.
